`ternal combustion engines upon motorvv vehicle frames. Themainobjectoftlie invention is the provision of a construction `which permitsof weaving and twisting ofthe motor vehicle frame in Aany directionwithout vplacing any stress upon the engine housing. f

The invention has for other objects the novel arangements andcombinations of parts as morefully hereinafter set forth.

In the dra-wings:

Figure 1 is a side elevation partly in sectionof a constructionembodying my invention' Figure 2 is a top plan view thereof;

Figure 3 is a cross section on the line 3--3 of Figure 1;

Figures 4 and 5 are views similar to Figures 1 and 3 respectively,showing a Inodified construction.

1 is a leg or projection extending laterally from lthe crank case of aninternal combustion engine. Thereare preferably three of these legs toprovide a three point Suspension for the engine, one leg being at thefront of the engine and the other two legs at the op- I1 the presentinstance the leg shpwn is at one side of the engine and supported uponside sill 2 of' the motor vehicle frame. 3 is a pivot plate rigidlysecured to the leg 1, by means of the bolt 4, which vertically passesthrough the outer end of the leg and threadedly engages the `:pivotplate, the nut 5 clamping the pivot plate against the lower tace of theleg. l The lower face of this pivot plate is convex both in a. directionparallel to the longitudinal axis of the engine and at right anglesthereto. 6 is a trunnion support having a concave face corresponding incurvature to the lower face of the pivot plate and engaging the saine,this trunnion support rotatably engaging in the bearing 7 rigidlysecured to the side sill 2.

For maintaining the pivot plate in engagement with the trunnion supportand at the sainev time permitting et relative rocking movement in anydirection, the coil springs are provided at opposite sides of the leg1andsurrounding the stud bolts 9, which pass through the pivot plate 3and are rigidflysecfln'ed" to the trunn'ion support G by being`tl-rreaded` thereinto. Nuts 10 thread- 'edly' eng-aging the upper endsoli the stud bolts' force the.` coil springs 8 against the pivot pla-te,suitable abutments 11, as w`ashers beingi preferably provided betweenthe coil springs andthe 4nuts andthe coil springs and the rocker arms.To permit of the ready moving ot' the parts, the apertures in thepiil'otlfilate lthrough which the stud bolts 9 pass are suiciently largeto provide sutlicient clearance to permit of the necessarv relativemovement of the pivot plate and trunnlon support.

As shown in the modification o'l,z Figures el and the pivot plate 12,which is secured to the leg 13 of the cra-nk case, is mounted upon asupport which is lixedly secured to the frame oi' the vehicle, insteadoiE being rotatably secured. In detail, the support comprises the pivotbearing 1l having a bearing face 15 which is concave both in a directionparallel to 'the longitudinal axis of the engine and at right anglesthereto and adapted to be rotatably engaged by the correspondinglyconvex bearing face of the pivot plate. Thispiv'ot bearing is mounted.upon the bracket 16 rigidly secured to the vehicle frame. The springpressed bolts 17 secure the pivot plate 12 and pivot bearing 14 to thebracket 16, the apertures in the pivot plate through. which the boltspass being` of sufficient size to permit ot the desired degree ofrocking of the pivot plate upon the pivot bearing.

'll/Vliet I claim as nay invention is;

1. The combination with an engine, of i frame, a pivot plate secured tosaid engin and having convex face curved in transverse direction, asupport rotatably mounted upon said frame and having a concave faceengageable with said convex tace.y and means engageable with theopposite end portions of said pivot plate for yieldably maintaining saidpivot plate in engagement with said support.

2. The combination with an engine, of a frame, a leg upon said engine, apivot plate Secured to the lower face of said leg, and having a lowerconvex face curved in transverse directions, a support having a concavesurface engageable with said convex -face and correspondingly curved,stud bolts secured to said support and extending through said pivotplate with clearancesy to permit of relative rocking movement of saidpivot plate and support7 and springs surrounding said stud bolts forforcing said pivot plate toward said support. p i i.

3. The combination with a motor, of a frame, a leg upon said motor, apivot plate having a lower face curved in vtransverse directions, meansfor fixedly securing said pivot plate to said leg, a support having aface curved in transverse directions and in engagement with the faceupon said pivot plate, and means upon opposite sides of said legI andconnected to said support for yieldably forcing said pivot plate'towardsaid support. A

4. The combination with a motor, of a frame, a trunnion supportrotatably mounted upon said frame, a pivot plate rockably engaging saidtrunnion support in a plane transverse to the direction of rotation ofsaid ifiiiaeee said pivot plate to said motor, andspringe upon oppositesides of said securing means for yieldably forcing said pivot plate `torWard said trunnion support.

The combination with an engine, of a traine, a leg upon said engine, apivot plate secured vto said "leg, a Support pivotally mounted upon saidframe and rockably engaging said pivot plate, and means upon oppositesides of said leg engageable` with said pivot platev forv yieldablymaintaining said plate in engagement With `said support. Y

6. The combination with a motor, of a fra-me, a legup-on said motor, apivot plate secured to said leg and having a convex face,

a support pivotally mounted on said frame and having a concave faceengaging the convex face of said plate, and means upon opposite sides ofsaid leg `l:tor yielilably main taining said `pivot plate in engagementwith said support. l

In testimony whereof li affix my signature.
